Abstract
An actuator device, a projection device including the actuator device, and a projection method applicable to the actuator device, are provided. The actuator device includes a base, a frame, an optical element, and at least one driving assembly. The projection method includes the following steps. The frame is disposed in the base, the optical element is disposed in the frame, and the at least one driving assembly is disposed between the base and the frame. The at least one driving assembly is controlled to drive the frame through a first signal, so that the optical element swings reciprocally relative to the base based on a first swing angle, a second swing angle, and a third swing angle of a first actuating shaft.

An actuator device, comprising:
- a base;
- a frame, disposed in the base;
- an optical element, disposed in the frame;
- at least one driving assembly, disposed between the base and the frame;
- and
- a controller, coupled to the at least one driving assembly,
- wherein the controller is configured to control the at least one driving assembly to drive the frame through a first signal, so that the optical element swings reciprocally relative to the base based on a first swing angle, a second swing angle, a third swing angle, and a fourth swing angle of a first actuating shaft,
- wherein the controller is configured to control the at least one driving assembly to drive the frame through a second signal so that the optical element swings reciprocally relative to the base based on a fifth swing angle, a sixth swing angle, a seventh swing angle, and an eighth swing angle of a second actuating shaft,
- wherein the fourth swing angle is greater than the third swing angle, the third swing angle is greater than the second swing angle, and the second swing angle is greater than the first swing angle, and
- wherein the eighth swing angle is greater than the seventh swing angle, the seventh swing angle is greater than the sixth swing angle, and the sixth swing angle is greater than the fifth swing angle.
A projection device, comprising:
- an illumination system, configured to emit an illumination beam;
- a light valve, located on a transmission path of the illumination beam, and configured to convert the illumination beam into an image beam;
- a projection lens, located on a transmission path of the image beam, and configured to project the image beam;
- and
- an actuator device, located on the transmission path of the image beam, and disposed between the light valve and the projection lens or disposed in the projection lens, wherein the actuator device comprises:
- a base;
- a frame, disposed in the base;
- an optical element, disposed in the frame;
- at least one driving assembly, disposed between the base and the frame;
- and
- a controller, coupled to the at least one driving assembly,
- wherein the controller is configured to control the at least one driving assembly to drive the frame through a first signal, so that the optical element swings reciprocally relative to the base based on a first swing angle, a second swing angle, a third swing angle, and a fourth swing angle of a first actuating shaft,
- wherein the controller is configured to control the at least one driving assembly to drive the frame through a second signal so that the optical element swings reciprocally relative to the base based on a fifth swing angle, a sixth swing angle, a seventh swing angle, and an eighth swing angle of a second actuating shaft,
- wherein the fourth swing angle is greater than the third swing angle, the third swing angle is greater than the second swing angle, and the second swing angle is greater than the first swing angle, and
- wherein the eighth swing angle is greater than the seventh swing angle, the seventh swing angle is greater than the sixth swing angle, and the sixth swing angle is greater than the fifth swing angle.
A projection method, applicable to an actuator device, wherein the actuator device comprises a base, a frame, an optical element, and at least one driving assembly, the projection method comprising:
- disposing the frame in the base, disposing the optical element in the frame, and disposing the at least one driving assembly between the base and the frame;
- and
- controlling the at least one driving assembly to drive the frame through a first signal, so that the optical element swings reciprocally relative to the base based on a first swing angle, a second swing angle, a third swing angle, and a fourth angle of a first actuating shaft;
- and
- controlling the at least one driving assembly to drive the frame through a second signal, so that the optical element swings reciprocally relative to the base based on a fifth swing angle, a sixth swing angle, a seventh swing angle, and an eighth swing angle of a second actuating shaft,
- wherein the fourth swing angle is greater than the third swing angle, the third swing angle is greater than the second swing angle, and the second swing angle is greater than the first swing angle,
- wherein the eighth swing angle is greater than the seventh swing angle, the seventh swing angle is greater than the sixth swing angle, and the sixth swing angle is greater than the fifth swing angle.
